V4L: Fix msp343xG handling regression

The msp3430G and msp3435G models cannot do Automatic Standard Detection,
so these should be forced to BTSC. These chips are early production
versions for the msp34xxG series and are quite rare.

Due to broken handling of the 'standard' option in 2.6.17, there is
no workaround possible.
